I'm looking for help please.....I have a 1994 Firebird (I know you guy's are a third gen site but I'm desperate!)3.4L that we are racing in a novice class on an oval track. The car needs to remain virtually stock. My problem is the car was completely rewired and I'm reinstalling the diagnostic plug for the scan tool. My PCM is #16184737 - from a PCM diagram that I do have which I believe is from a V8 Camaro (see link - http://www.v6f-body.com/showthread.php?t=689 ) Someone told me that I only need 2 wires - "A" and "M" of the diagnostic plug? I've done that but still have no communication between the scanner and the computer. I have direct leads running to the PCM - "A" going to "B16 & B32" ECM ground and "M" going to "B19" Serial Data. Also from that diagram on the link, I don't have an "F" lead from the diagnostic plug but one coming from the pin below which I think is "G" (black/white) which I have no idea where it is supposed to terminate. Also the diagram shows the diagnostic enable on C9. My problem is there is no wire on my C9 connector. This PCM and wiring harness are original to the car, the diagnostic plug was cut out (also original to car) so I couldn't trace it back. My PCM is #16184737 - PLEASE HELP!



Thanks
